Description

Technical Field

[0001] The invention relates to the field of processing fluoroplastics for aviation, in particular to a quick shearing device for cutting fluoroplastic gaskets with multiple specifications and multiple angles. Background Art

[0002] Fluoroplastic is widely used in electronics, medical, aerospace and other fields due to its excellent high temperature resistance, corrosion resistance, wear resistance, insulation and other characteristics. Fluoroplastic gaskets are often used in aviation hydraulic pipelines. They are installed on both sides of the rubber sealing ring to prevent the risk of oil leakage in the system. The quality of the cut of the fluoroplastic gasket will directly affect the sealing effect of the system.

[0003] At present, fluoroplastic gaskets of multiple specifications and multiple angles are mainly processed by single specific tooling and hand-held blades. Each specification of fluoroplastic gaskets needs to be made of a separate tooling. When the outer dimensions and cutting angles change, new tooling must be made. This cannot meet the universal requirements. At the same time, the processing operation is time-consuming and labor-intensive, which increases the manufacturing cost. The use of hand-held blades for cutting cannot ensure the uniformity of quality, which is inefficient and also poses certain safety risks. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a quick shearing device for cutting fluoroplastic gaskets with multiple specifications and multiple angles.

[0005] A quick shearing device for cutting fluoroplastic gaskets of various specifications and angles, comprising:

[0006] Angle adjustment mechanism, rotate to the required angle according to the actual needs of the parts;

[0007] The cutting mechanism is connected with the angle adjustment mechanism, thereby achieving linkage between the cutting mechanism and the angle adjustment mechanism;

[0008] The positioning and clamping mechanism plays the role of positioning and clamping parts.

[0009] The angle adjustment mechanism comprises a base and an L-shaped support rod connected to the base by bolts to control the angle position.

[0010] The beneficial effects of the present invention are as follows: for fluoroplastic washers with different specifications and cuts at different angles, in order to keep the parts, blades and base angles in relatively accurate positions during cutting, bolt four, gasket one, bolt six and gasket three can be turned to adjust the side vertical plate left and right, and bolt five and gasket two can be turned to adjust the height of the supporting baffle. The working position of fluoroplastic washers with different specifications and cuts at different angles can be met by adjusting left and right and up and down. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below.

[0021] like Figures 1 to 7 As shown, a quick shearing device for cutting fluoroplastic gaskets of multiple specifications and multiple angles comprises:

[0022] Angle adjustment mechanism, which rotates to a desired angle according to the actual needs of the part 12;

[0023] The cutting mechanism is connected with the angle adjustment mechanism, thereby achieving linkage between the cutting mechanism and the angle adjustment mechanism;

[0024] The positioning and clamping mechanism plays the role of positioning and clamping the part 12.

[0025] The angle adjustment mechanism includes a base 1 and an L-shaped support rod 2 connected to the base 1 by a bolt 3 to control the angle position. By tightening the bolt 3, a gap is created between the base 1 and the L-shaped support rod 2. The bolt 3 rotates in the groove of the base 1 to drive the L-shaped support rod 2 to rotate. The angle of the base 1 is observed by the pointer on the L-shaped support rod 2. When it is rotated to the desired angle, the bolt 3 is tightened to fix it, thereby achieving the effect of angle adjustment, which is convenient and easy to operate.

[0026] The base 1 is provided with an arc groove and an angle display interface matched with the arc groove to adjust the relative angle position of the blade 7 and the part 12. At the same time, the angle can be directly read in the base 1, which is convenient for operation and meets the needs of different incisions.

[0027] The incision mechanism includes a pressure rod 6 connected to the L-shaped support rod 2 through a rivet 8, a knife rod 4 set on the pressure rod 6 through a bolt 5, and a blade 7 set on the knife rod 4. The blade 7 is pressed into the slot of the knife rod 4 through the bolt 5 and the pressure rod 6, and the bolt 5 is turned to fix it. At the same time, the incision structure is connected to the angle adjustment mechanism through the rivet 8, thereby achieving linkage between the incision mechanism and the angle adjustment mechanism.

[0028] The support baffle 13 is provided with a protective cotton pad 15 to prevent the blade 7 from directly contacting the support baffle 13 and damaging the blade 7 and the surface of the support baffle 13 .

[0029] The positioning and clamping mechanism includes a supporting baffle 13 for fixing parts 12 of different specifications, a pressing plate mechanism 11 which is pressed on the supporting baffle 13 together with the parts 12 through bolt three 9 and spring 10, and an adjusting side plate 14 which is installed on the base 1 through bolt four 16, gasket one 17, bolt six 20 and gasket three 21.

[0030] For fluoroplastic washers with different specifications and cut angles, in order to keep the angles of part 12, blade 7 and base 1 in relatively accurate positions during cutting, bolt four 16, gasket one 17, bolt six 20 and gasket three 21 can be turned to adjust the side plate 14 left and right. By turning bolt five 18 and gasket two 19, the support baffle 13 can slide in the vertically arranged groove of the side plate 14 to achieve the purpose of adjusting the height of the support baffle 13. The working position of fluoroplastic washers with different specifications and cut angles can be met by adjusting left and right and up and down.

[0031] The side plate 14 is provided with two sets of slide grooves respectively matched with the bolt four 16 and the bolt six 20.

[0032] The side plate 14 is also provided with bolts 5 18 and gaskets 2 19 that cooperate with the support baffle 13. The side plate 14 and the support baffle 13 are connected by bolts to adjust the spatial position of the part 12. At the same time, the bolts 5 18 are adjusted to achieve the linkage between the blade 7 and the part 12 in space.

[0033] The pressing plate mechanism 11 comprises a pressing plate 11.7, a ratchet wheel 11.2 and a ratchet wheel 11.5 respectively arranged at both ends of the pressing plate 11.7, a movable baffle 11.1 and a movable baffle 11.6 respectively connected to the ratchet wheel 11.2 and the ratchet wheel 11.5, and a spring 11.3 and a spring 11.4 respectively connected to the movable baffle 11.1 and the movable baffle 11.6. The ratchet wheel 11.2 and the ratchet wheel 11.5 are controlled by turning a knob 11.8 and a knob 11.9, and the elasticity of the spring 11.3 and the spring 11.4 is used to control the expansion and contraction of the movable baffle 11.1 and the movable baffle 11.6, so as to adapt to fluoroplastic washers of different specifications and play a role of limiting.

[0034] The end surface of the pressure plate 11.7 away from the spring 11.3 and the spring 11.4 is provided with a knob 11.8 and a knob 11.9 connected to the ratchet 11.2 and the ratchet 11.5 respectively. The ratchet and the spring cooperate to adjust the overhang of the pressure plate 11.7 to adapt to parts of different specifications and sizes.

[0035] The pressing plate 11.7 is provided with two groups of grooves for installing the spring 1 11.3 and the ratchet 1 11.2, the spring 2 11.4 and the ratchet 2 11.5 respectively, and the elastic force of the spring 1 11.3 and the spring 2 11.4 is used to press the part 12.
